16k and rear axle is leaking

high country · June 29, 2015

Noticed today while washing the truck the RR wheel has gear oil on the inside of the rim. Crawled under the truck and the RR wheel seal is going. Gear oil over the tire, rim, back plate etc. Gear oil everywhere. I cannot believe that a new truck with 16k on the clock has a RR axle seal going bad. My '94 Toyota made it to 140k and then I rebuilt the axle when I did gears and lockers. Well, I need to take it in to the dealer, and hopefully get a loaner.

So it is all fixed up?

^Been fixed. Took them 4 hrs. I have about 10-11k more miles on the truck. Yes, I drive a lot. Leak free my friend. At my next oil change 30-32k I plan on doing the front and rear diff. I've been using 4WD a lot at work. At my last oil change I topped off front and rear diffs with M1 75/90 that I had in the garage. Front diff was a bit low IMO. But both diff fluids look very clean. I wipe the magnet on the rear diff... M1 or Synpower 75/90 is going in F&R diffs soon...

What is the purpose of this thread?

You took the truck to the dealer, under what appears to be warranty, and they denied you an acceptable means of fixing the problem?

Or - you immediately complained on an internet forum about a mass produced vehicle having an issue that now apparently is being taken care of at your dealer?

What did you expect to get in between your original post and going to the dealer? Every reasonable response would have been "go to your dealer".

Easy man, he didn't force you to read it. Maybe he was trying to let people know to look out for this around 16K miles.

^exactly. If you catch it early enough the brake pads won't get damaged either.

Back to leaking again. Noticed it this weekend when doing the PML cover. Leak is not bad, but it's wet for sure. 43.5k now on the clock. Same RR axle seal. WTF.

I had a new 98 2500 Silverado that had a leaking axle seal that would get changed, then start leaking again after about a month of driving (2000 miles). It got changed 4 times along with the entire housing, using my original guts. Clearly the axle seal surface that rode on the seal was wearing out the seal. The series of dealers and GM customer service never were organized enough to figure it out, nor listen to me. Chevrolet bought that truck back after a year.

My 2016 Chevrolet Silverado pinion shaft seal is leaking at 13,000 miles.The truck has had the vibration problem since brand new.My 4th attempt to repair it this Tuesday.If GM fails again to rectify this problem this time.I am going to litigation for the buy back

My 2016 Silverado 1500 has 13,500 miles with leaking differential at the spline and yoke

Well that stinks also. That's a bigger job than an axle seal. I'm at 72k+. Mine still seeps. I have bigger fish to fry in life and it's not an issue that is actually big enough to flip out over. Plus I rather do the job and know it's fixed correctly.
